Here comes the bride!
The 32-year-old Star Trek actress first dated Cowper-Smith when they were teenagers attending the Westminster School in London together. They eventually parted ways. Eve later reportedly dated poet Adam O'Riordan after attending Oxford together, but they broke up in 2012.
Eve made her big box office debut in the U.S. with her role in 2010's Sex and the City 2.
Since then, Eve has appeared on Entourage and starred in hits like Men in Black 3 and Star Trek: Into Darkness.
Congrats, you two!
